Message

At Pentalog, I implemented debit card functionality in an Austrian banking app and extended fiat and crypto withdrawal flows, including multi-chain transfers. I also supported these features as fintech regulations and product requirements evolved.

I took ownership of complex legacy features, documenting how they worked and identifying technical and product limitations before proposing scalable rework. I worked with product owners and designers to resolve flow issues and improve customer experience in critical financial operations.

Earlier at Pentalog, I built a Flutter OCR app for recruiters from scratch and led a small team of Flutter and backend developers. At Endava, I developed a reusable Android SDK and implemented BLE beacon-based indoor navigation.
